Choosing a new HDD in 2011 Laptop

[mickyxtoo]

Hi everyone, I'm a new member.
I've an HP DV6-6178sl of 2011. I saw that the HDD is going to leave me so I've thought to change it (I think it's time, they've been 6 years...). For storage reasons I need an HDD because of the smaller capacity of today's SSD and I'm undecided about this two hdd:

1) WD Black 500gb 7200rpm
2) Seagate Firecuda 1Tb 5400 rpm.

I read that although the second one has a 5400 rpm it doesn't lower the performances. Is it true? Because if yes I would choose the second one to have more storage and also because it seems the right compromise between an HDD and SSD (reading on the Seagate's website).

Ps. My PC has:
CPU: Intel Core i7-2670QM (2.20 GHz / 3.10 GHz, 4 core, 6 MB CACHE L3).(info)
Graphic Card:AMD Radeon HD 6770M 2 GB GDDR5.(info)
HARD DISK: Toshiba 640 GB SATA 5400 rpm.
RAM: 8 GB DDR3 1333 MHz (2 x 4 GB) max 8 GB.

Hm.

I'm not sure how to stress this enough:

DON'T BUY THE SEAGATE DRIVE.

put a SSD in your main drive bay, get an optical drive bay adapter that will allow you to put a regular hard dive in there. Best of both worlds. you don't need a DVD drive really do you? you can buy external dvd drives for the rare cases you do.

Northwind: Neither firecuda? Few months ago I bought a 1tb barracuda for my home PC: I've to change it?
HaQue: It's an amazing solution! I'll take a look, thanks a lot

Ok, I think I'll buy an HGST 7K1000 1TB.
